oh BOLD where art thou? Evidence for a "mm-scale" match between intracortical and fMRI measures.

A frequently discussed problem with functional magnetic resonance imaging is that we don’t really understand how the hemodynamic ‘activations’ measured by the technique relate to actual neuronal phenomenon. 782 more words

Increased levels of the body’s own cannabinoids impair embryonic brain development.

The human body produces substances, called endocannabinoids, that work in a similar way to cannabis. These endocannabinoids may not produce a ‘high’, but are of tremendous importance for the functioning of the neural network in the brain, especially during the embryonic stage. 311 more words
